n (ah, how to describe these…) bit of fancily-coloured paper wrapped much like a lozenge, with twisted ends. A small sort of explosive device is put inside a cracker so that when two people pull at alternate ends, the whole thing comes apart with a snapping noise and — ah, the joy — a small piece of trinket crap falls out. This will be something like an ineffectual miniature sewing kit, a set of blunt nail clippers or one of these mysterious “get the bits of metal apart” puzzles, which will cause some degree of interest from the surrounding family until someone realises it’s very easy to get them apart because it was made in China and came out of the factory bent. As the name suggests, these are mainly used at Christmas but sometimes pop up at birthday parties and the like.
